How many nuclei does the trigeminal nerve have?
Unlike the other cranial nerves, the trigeminal nerve is quite large. It has four nuclei that send fibers to form its tracts and is associated with three separate branches. Key facts about the trigeminal nerve (CN V) Type. Mixed (motor and sensory) Nuclei. Motor nucleus of trigeminal nerve.
How do axons form the mesencephalic tract?
As the myelinated axons leave the mesencephalic nucleus, they coalesce to form the mesencephalic tract. The individual axon s then split into central and peripheral branches. The central branches convey impulses from the neuromuscular spindles within the muscles of mastication, and from the bite force reflex arcs, to the motor neuron of the trigeminal nerve. Other central fibers also integrate with the reticular formation and the sensory trigeminal nerve. Others also gain access to the cerebellum by way of the superior cerebellar peduncle. This interplay between the proprioceptive and motor divisions of the trigeminal nerve helps to regulate the activity of the stretch muscles; and by extension, the process of mastication.

Where does the trigeminal nerve originate?
The motor division of the trigeminal nerve derives from the basal plate of the embryonic pons, and the sensory division originates in the cranial neural crest. Sensory information from the face and body is processed by parallel pathways in the central nervous system .
What are the areas of cutaneous distribution of the trigeminal nerve?
The areas of cutaneous distribution (dermatomes) of the three sensory branches of the trigeminal nerve have sharp borders with relatively little overlap (unlike dermatomes in the rest of the body, which have considerable overlap). The injection of a local anesthetic, such as lidocaine, results in the complete loss of sensation from well-defined areas of the face and mouth. For example, teeth on one side of the jaw can be numbed by injecting the mandibular nerve.

What is the name of the nerve that is disrupted by blood pressure?
In trigeminal neuralgia, also called tic douloureux, the trigeminal nerve's function is disrupted. Usually, the problem is contact between a normal blood vessel — in this case, an artery or a vein — and the trigeminal nerve at the base of your brain. This contact puts pressure on the nerve and causes it to malfunction.
